A study led by a neurologist from McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth) showed that a computed tomography (CT scan) could be sufficient for determining thrombectomy treatment in stroke.

Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command — simply by shining a light on them and varying its intensity. The cells are grown on a material called graphene, which converts light into electricity, providing a more realistic environment than standard plastic or glass laboratory dishes.

Researchers from Washington State University have discovered how a genetic mutation linked to hypertrophic cardiomyopathy disrupts the heart’s normal function. The study, which will be published May 18 in the Journal of General Physiology, reveals that the mutation prevents the heart from increasing the amount of force it produces when it needs to pump additional blood around the body.

A new study compared EMS use of endotracheal intubation versus a laryngeal tube for patients with out-of-hospital cardiac arrest. Results indicate increased survival rates with use of the laryngeal tube.

In a landmark study, researchers found that patients treated with paramedic oxygen delivery using a newer, more flexible laryngeal breathing tube may have a greater survival rate after sudden cardiac arrest than the traditional intubation breathing tube.

Chris Scholten arrived at a community hospital with stroke-like symptoms. Using telemedicine technology, a Loyola Medicine stroke specialist examined Mr. Scholten remotely and recommended he be transferred to Loyola, where he underwent life-saving brain surgery.

By analyzing reported physical activity levels over time in more than 11,000 American adults, Johns Hopkins Medicine researchers conclude that increasing physical activity to recommended levels over as few as six years in middle age is associated with a significantly decreased risk of heart failure, a condition that affects an estimated 5 million to 6 million Americans.

A new study reveals that essential fats in the diet may play a role in regulating protein secretion in the muscles by changing the way genes associated with secretion act. The study is published ahead of print in Physiological Genomics.
